I ended up following the post you made here:
And installing this zip:
https://github.com/zach-morris/kodi_libretro_buildbot_game_addons/raw/main/repository.kodi_libretro_buildbot_game_addons_le_armhf.zip
After that the Emulators folder was there. Also enabled Libretro Compatibility and rebooted a few times.
I’ve tried a few Snes9x emulators (Current, 2010, 2005 Plus etc) and I’ve noticed that the ROM stutters continuously, right from startup. If I keep restarting the ROM eventually it will play ok but it’s completely random. No idea how to fix it.
It’s definitely not the ROM itself as it works fine elsewhere.
When it works, it works perfect. Just no idea where to go to fix that last issue.
